AUTOMATIC FEED-WATER REGULATOR.

SPECIFICATION forming part 0f Letters Patent No. 723,653, dated March24, 1903. Application led November 3v, 1902. Serial'No. 129,830. (Nomodel .To all whom it may concern;

Be it known that I, HARRY COOK, a citizen of the United States ofAmerica, residing at McKeesport, in the county of Allegheny and State ofPennsylvania, have invented certain new and usefullmprovements inAutomatic Feed-Water Regulators, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements inautomatic feed-Water regulators, and has for its object the provision ofnovel means whereby when the wa-V ter in the boiler lowers beyond thewaterline which it is desired to maintain the valve or valvescontrolling the feed-line will be automatically opened so as to admitthe water to the boiler and again raise the saine to the desiredwater-line and also to automatically close the valve or valves when thedesired water-line has been reached.

-A further object of my invention is to provide means whereby the waterwill not bev discharged into the boiler in its cold state, but will beheated to a vconsiderable Yextent before being discharged into theboiler.

Still further objects of my invention are to provide a perfectlybalanced-valve, and other objects reside in the novel construction,combination, and arrangement of parts to be hereinafter more fullydescribed, and specifically pointed out in the claims.

In describing the invention in detail reference is had to theaccompanying drawing,

forming a part-ofthis specification, which drawing shows a verticalsectional'view Aofmy improved water-regulator applied in po` sition on aboiler..

To put my invention into practice, I provide a valve body or casing 1,provided with an inlet 2, leading to the valve-chamber 3. Thewater-supply pipe 4 communicates with the inlet-port, being connected-tothe valve body or casing in any desirable or suitable manner, such asshown. The valve body or casing is provided with a pair of valve-seats5, and communication is established from below the lower valve 6 to thechamber 8 above the upper valve 7 through a port orv by-pass 9 in thevalve body or casing. A union 10 is suitably connected to the lower endof the valve body or casing, and this union is also securely fastened bythe flange 1l and bolts passing therethrough to the boiler-casing 12,the Vunion having an interiorly-threaded nipple 14,'extending throughthe boilercasing 12 and-receivingthe'tubular extension 15, which isthreaded therein and` extendsinto the boiler.. VThis tubular extension15 is provided with an opening at one side and with a pair of lugs orears 16, iu which is pivoted the lever-17, the one end of which ispivotally connected to the valve-stem 18 and the outervend of which.lever carries a float 19, the threaded stem 20 of which is threadedinto the outer end of the lever andV carries nuts 2122 above and belowthe latter, whereby the iioat may be adjusted to the desired height.This float in practice is preferably made of a hollow copper ball, asthis has been found to be the most desirable material.

The tubular extension 15 is provided with a flared or bell-shaped lowerend 23, which is provided with slots or openings 24 to permit the waterto escape from the tubular extension 15 into the funnel-shapedreceptacle 25, which is carried on 'the screw-pin 26, secured to thelower end of the tubular extension 15, this screw-pin also carrying thecorrugated pan 27, the pan and the funnel-.shaped receptacle beingsecured on the pin by means of thenut 28.

The valve-stem 18 at its upper end carries a socket 29, provided with astuffing-box 30, through which passes the regulating-stem 31. Thisregulating stem 3l passes through a cover-plate 32 of the valve body orcasing 1, through a suitable stuliingbox'33, carried by said top plate,and .through a support 34: and is provided on its upper end with asuitable handle or operating-wheel 35. f The Vregulating-stem at itslowerend is provided with a head 36, which operates-in the socket'or cup29, carried by the valve-stem ,18. f

In operation thewaterloWiug-through the inlet 2 will, providing theWater-line in the boiler has lowered beyond the desired level, flowthrough the valve-body and through the tubular extension 24 into thereceptacle 25. When this receptacle is filled with water, it isdischarged onto the corrugated pan and liows into the boiler. Valves 6and 7 will be open, due to the fact of the water-line being below thevdesired -level and the float 19 being IOO consequently disengaged, soas to elevate the valve-stem 18 and open the valves 6 and '7. As thewater reaches the desired level and the iioat 19 is carried upwardlythereby the valves 6 and 7 will be vcnt ,lfaged'with their seats, and byreason cf the Water having been restricted during its flow into theboiler it will pass through by-pass orport 9 above the valve 7, andconsequently maintain a perfectly balanced valve. It desired, the stem3l may be screwed down so that the head 36 thereof will rest against thebottom of the socket or cup 29, so as to retain the valves in theirclosed position. The water being restricted in its passage, it becomesheated before being discharged into the boiler, and the drip-pan beingcorrugated the same flows o this pan slowly instead of being dischargedrapidly therefrom. l

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In an automatic feed-water regulator, the combination with avalve-body having a pair of Valve-seats and provided with a bypass orport establishing communication with chambers above and below thevalve-seats, said valve-body having an inlet-port, a valvestem, and apair of valves mounted on the said stem, and a tubular extensionconnected to the valve-body and provided at its lower end withoutlet-ports, and a oat pivotally connected to the tubular extension andthe valve-stem, substantially as described.

2. In an automatic feed-water regulator, a valve-casing provided with aninlet-port, a pair of valve-seats in said casing, and a port or by-passin said casing. establishing conlmunication above and below thevalveseats, a valve-stem extending through the valvebody, a pair ofvalves carried by said stem to engage the seats, a socket or cup carriedby the upper end of said valve-stem, a regulating-stem connected to saidcup or socket, a tubular extension connected to the lower end of thevalve -body and extending into the boiler-shell, and an adjustable iioatpivotally connected to the tubular extension and valvestem,substantially as described.

3. In an automatic feed-water regulator, the combination ofavalve-bodyprovided with an inlet-port, a pair of valve-seats, a by-passin the valve-body establishing communica'- tion above and below lthevalve-seats, a valvestem, a pair of valves on said stem to engage thevalve-seats, an adjusting-stem connected to the valve-stem, a tubularextension connected to the lower end of the valve-body, an adjustablefloat pivotally connected to the tubular extension-and to thevalve-stema funnel -shaped receptacle carried by the lower end of thetubular extension, and a corrugated drip-pan carried bythe extensionbelow the funnel-shaped receptacle, substantially as described.

4. In an automatic feed-water regulator, the combination with thevalve-body, formed with an inlet-port and a valve-seat, a tubularextension connected to the said valve-body, a valve-stern, a fioatoperatively connected to ssL the said valve-stem, a receptacle carriedby the lower end of the said tubular extensionv and a drip pan arrangedadjacent said receptacle.

In testimony whereof I affix my signature in the presence of twowitnesses.
